    The APY never came as a large port APY was small port as well as BAM

    AEB and AGU are the main large port heads to look out for.

    Do a search and you will find all the info needed about the swaps.

    With your spec your best fitting a hybrid, manifold, 440/550cc injectors and then you'll be flying

    Yes but a ported small port will not flow as much as a standard large port

    Instead of starting numerous threads asking questions that are all related to your engine build it might have been better to stick it all in one?? retains a little context then and neither you or people replying will need to repeat themselves :)

    APY is small port and even a ported small port won't flow the same as a large port... porting a small port does not make it a large port... ever :)
